Provided is an electric all-wheel drive vehicle in which a front wheel is directly driven by a front motor and a rear wheel is directly driven by a rear motor, and in a high vehicle speed range in which the output torque of the front motor and the rear motor is low, when an accelerator pedal is depressed, an acceleration feeling that is equal to or greater than the vehicle acceleration that is actually generated can be given to a driver. An electric all-wheel drive vehicle (1) is provided with: a front motor generator (21) that directly drives front wheels (10FL, 10FR); a rear motor generator (22) that directly drives the rear wheels (10RL, 10RR); and an EV-CU (60) that controls the driving of the front motor generator (21) and the rear motor generator (22) on the basis of the operation amount of the accelerator and the vehicle speed. The EV-CU (60) changes the front-rear distribution of the driving force toward the rear wheel load side when the operation amount of the accelerator increases at or above a predetermined speed in a state where the vehicle speed is at or above the predetermined speed.

    本发明提供一种电动式全轮驱动车,由前电动机直接驱动前轮且由后电动机直接驱动后轮,在前电动机、后电动机的输出转矩低的高车速范围,在加速踏板被踩踏的情况下,能够给予驾驶者实际产生的车辆加速度以上的加速感。电动式全轮驱动车(1)具备:前电动发电机(21),直接驱动前轮(10FL、10FR);后电动发电机(22),直接驱动后轮(10RL、10RR);以及EV‑CU(60),基于加速器的操作量及车速控制前电动发电机(21)及后电动发电机(22)的驱动。当在车速为预定速度以上的状态下,加速器的操作量以预定速度以上增大时,EV‑CU(60)使驱动力的前后分配向后轮偏重侧变化。
